If you’re requiring returning employees to test negative, please pause
This morning, Emma Employee was exhibiting symptoms of COVID-19. You did the right thing and sent her home. Now you wonder when she can return to work, because she is great at her job, and you really need her. As part of this consideration, you wonder if you can require Emma to have a negative test result before returning to work. After all, you want to make sure the nasty little virus stays out of your facility.
Such a mandate is sooo last week!
On July 20, the CDC indicated (in non-scientific, employment-law-nerd speak) that, while an individual might still have the virus inside them for up to 12 weeks, it is not replicating, so the individual is not contagious. It just takes some weeks for the body to get rid of the non-active virus particles. This is referred to as “shedding” (for any of you who will go on to read more about the science).
Now, the CDC indicates that persons with mild to moderate COVID-19 remain infectious no longer than 10 days after symptom onset. Persons with more severe to critical illness or severe immunocompromise likely remain infectious no longer than 20 days after symptom onset.
These new findings support relying on a symptom-based, rather than test-based strategy for ending isolation of these individuals. This way, if they are no longer infectious, they are not kept unnecessarily isolated and excluded from work or other responsibilities.
Maybe Emma can return to work sooner than expected.
Given all this, the current evidence shows that most employees with COVID-19 symptoms may return to work when they meet the following criteria:
- Ten days have passed since symptoms first appeared,
- They have no fever for at least 24 hours without the use of fever-reducing medications, and
- Other symptoms have improved.
Some employees with severe illness may be contagious beyond 10 days and should not return to work until 20 days after symptom onset, in consultation with infection control experts.
Employees who never develop symptoms may return to work 10 days after the date of their first positive COVID test. Again, a negative test results might not be very effective, so mandating them would be counterproductive.
Employees who have been exposed should continue to quarantine for 14 days from the date of exposure.
Some good news is that, six months after the emergence of virus, there have been no confirmed cases of reinfection.
The learning curve remains as we see continue to see change at the speed of science. Stay tuned!
